Bearing fault detection and fault size estimation using fiber-optic sensors
Mechanical systems and signal processing, 2019Health monitoring of rotating machinery is commonly based on vibration signals. Instead, this pioneering research provides bearing diagnostics using strain measurements, obtained from Fiber Bragg Grating (FBG) fiber-optic sensors.

Fiber optic technology started in 1970’s, for long distance telecommunications, and it has experienced an exponential growth during the last four decades. Sensing applications are a small spin-off from this technology, taking profit of developments done for optoelectronic components and concepts. Optical fibers are cylindrical dielectric waveguides for
